A kind of Multi-axial Loading test device of finite element analysis, it is to generate Multi-axial Loading by computer motion control, to being bent, reversing by geodesic structure, shear, tension and compression deformation, each wet environment value is obtained by displacement sensor, measuring each measuring point by strain transducer strains.The device is easy to operate automatic, is suitable for the high-precision slow test of various structures.
Description
Technical field：
The utility model is related to a kind of finite element analysis device, specifically a kind of multiaxis of finite element analysis adds
Carry test device.
Background technology：
Many engineering structures are required for carrying out the structural member on slow test, especially space satellite.It is common quiet
Power experiment is loaded using testing machine or hydraulic jack, and the generally unidirectional load of testing machine once carries out one or two direction
Bending, shearing, torsion, tension and compression, hydraulic jack can simultaneously load with multiple, but control accuracy and operating characteristics compared with
Difference.
Utility model content：
Add the purpose of this utility model is that providing a kind of multiaxis of finite element analysis in view of the deficiencies of the prior art
Carry test device.The device, which is adopted to computerized control, carries out Multi-axial Loading measurement, high certainty of measurement, high degree of automation, operation
It is easy.
The technical solution of the utility model：
Tested structural member is fixed on load table top, and load tooling, which is fixed on to be tested, ties end；Tension and compression loading arm upper end is solid
It is scheduled on frame, lower end acts on load tooling upper end；Torsion loading arm acts on load tooling both ends in the horizontal direction；Bending
Loading arm acts on load tooling both ends in vertical direction；Shearing loading arm acts on load tooling one end in the horizontal direction；By
Computer passes through motion control card control tension and compression loading arm, torsion loading arm, bending loading arm, shearing loading arm；Strain sensing
Device and displacement sensor are connected to computer；Computer disposal obtains the Static Test Results of tested structural member.
The utility model has the beneficial effects that：Compared with the prior art, the utility model is a kind of based on computer control
The automatic testing equipment of motion control card progress multipoint excitation, high certainty of measurement, high degree of automation are easy to operate.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model.
It is marked in figure：1 tension and compression loading arm, 2 torsion loading arms, 3 bending loading arms, 4 shearing loading arms, 5 frames, 6 loads
Tooling, 7 tested structural members, 8 strain transducers, 9 displacement sensors, 10 computers, 11 motion control cards.
Specific implementation mode：
As shown in Figure 1, a kind of Multi-axial Loading test device of finite element analysis.Including 1 tension and compression loading arm, 2 torsions add
Load arm, 3 bending loading arms, 4 shearing loading arms, 5 frames, 6 load toolings, 7 tested structural members, 8 strain transducers, 9 displacements pass
Sensor, 10 computers, 11 motion control cards.
The tested structural member 7 is fixed on load table top, and load tooling 6 is fixed on 7 upper end of tested structural member；It draws
1 upper end of pressure loading arm is fixed on frame 5, and lower end acts on 6 upper end of load tooling；Torsion loading arm 2 acts in the horizontal direction
At 6 both ends of load tooling；Bending loading arm 3 acts on 6 both ends of load tooling in vertical direction；Loading arm 4 is sheared in level side
6 one end of tooling is loaded to acting on；By computer 10 by motion control card 11 control tension and compression loading arm 1, torsion loading arm 2,
It is bent loading arm 3, shearing loading arm 4；Strain transducer 8 and displacement sensor 9 are connected to computer 10；Computer 10 is handled
To the Static Test Results of tested structural member 7.
The Multi-axial Loading test device operation principle of the finite element analysis is：Motion control is stuck in computer control
Bending, shearing at lower driving different role point, torsion, tension and compression loading arm can be individually bent according to needs are measured, cut
It cuts, reverse, the subitem slow test of tension and compression, the slow test of bending, shearing, torsion, tension and compression can also be carried out at the same time, strain passes
Sensor and displacement sensor test result are automatically saved in computer.
